Most free slime games are slime makers, where you stretch, colour and squish virtual slime for the ASMR feel, led by Super Slime Simulator with more than 100M installs. The rest are slime pets, tower defence, idle and puzzle games starring slime characters, and two of those are rated Everyone 10+ or Teen.
Slime had its moment as the craft that took over every kitchen table, and plenty of parents still find glitter in odd places. A slime app gives children the squish and the satisfying sounds with none of the clean-up.
I read the Google Play listing for each game and noted the developer, the installs, the content rating, the ads and in-app purchases labels, and any offline wording. They're in no set order.
Not every game with slime in the name is a slime maker. About half of this list is action, idle or puzzle games where slime is the hero or the enemy, so I've marked which is which below.

Squishing through each game

Bruno - My Talking Slime Pet
From the same developer, this one turns slime into a virtual pet called Bruno that you look after. It suits children who like pet games as much as slime.
Slime Art: Relaxing ASMR
A 3D art and design game where you make realistic slime and play with it for that oddly satisfying feeling. The listing pitches it as a way to relax.

Slime Castle - Idle TD Game
A tower defence game where you play a slime defending the forest from invading humans, collecting equipment as you go. It's rated Everyone 10+.
Slime Legion
A merge game where you play a great devil defending a monster forest: merge your monsters, set a lineup and protect your castle. It's rated Teen.
Slime Games: Satisfying ASMR
A DIY slime simulator with craft activities and ASMR sounds. It shows neither a Contains ads label nor an in-app purchases label.
Slime Evolutionary Path - Idle
A relaxing indie idle game made by one developer: you're a slime choosing an evolution path, learning skills and taking on enemies. The listing says progress continues while you're offline.
Cat Squad: Slime Rush
A one-thumb horde shooter: your cat fires on its own while you move, and each wave brings more slimes. It's a small game, at 5K+ installs.
Slime Blast
A puzzle game where you spread colourful slime and set off chain explosions to reach level goals. It's tiny, at 100+ installs, and shows no ads or in-app purchases labels.
Slime makers versus slime adventures
Slime makers (Super Slime Simulator, Slime Art, Squishy Slime Maker For Kids and Slime Games: Satisfying ASMR) are about the feel and the sound. There's no winning; you mix, colour and squish until you're happy.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Slime pets like Bruno - My Talking Slime Pet add care and personality, a bit like a virtual pet with a stretchy twist.
Slime adventures (Slime Castle, Slime Legion, Slime Evolutionary Path, Cat Squad: Slime Rush and Slime Blast) borrow slime as a theme for tower defence, merging, idle, shooting and puzzle play. These suit older children and grown-ups more than the makers do.
Why slime apps feel so calming
The makers lean heavily on ASMR: soft squelches, pops and slow stretching. Many listings pitch them as a way to relax or ease stress, and for some people the sound alone is the point. Headphones help, and they spare the rest of the house.
If you love that unhurried feeling, you might enjoy more puzzle games that are relaxing, not stressful, and a wider look at cozy games for slow evenings.
Ads and ratings for younger players

For a young child, the three apps without an ads label are the easiest place to start. If you're setting up a tablet for them, my guide to free offline games for a kid's Android tablet covers the settings worth changing first.
Real slime or the app?
An app won't replace the joy of mixing a real batch, but it's a good stand-in on a rainy afternoon, in a waiting room or when nobody fancies scrubbing the table. Some families use the app to plan colours and mix-ins before a real slime session at the weekend.
